### 5/5 — Singing aid

*2024-07-15*

I have been looking for something like this.
I noticed when I heard recordings of myself singing with an instrument, my voice sounded a little off, and I always felt it was flat, but I could not figure out how to measure or consistently correct this in the moment.
With this app I can hit a note on an instrument and try to match it with my voice. I was able to see I was 3 Hz (26 cents)flat consistently. I will try to use this app to retrain my ear so as to sing more in the “pitch pocket”.
